| 摘 要： | 利用大连地区近30年干旱、暴雨、冰雹等气象灾害观测资料,采用协同克里金、光滑薄片样条等方法,对大连地区主要的农业气象灾害进行空间化。结合1∶250000大连市地理信息资料,采用ArcMap软件对农业气象灾害进行空间分析,并制作了灾害分布和作物信息叠加的专题图。以冰雹灾害和作物产量分布为例,详细阐述了农业气象灾害空间化方法的应用。研究结果可为大连地区制定防灾减灾规划、优化农业种植布局提供决策依据。

| Abstract: | By using the observation data of drought,torrential rain and hail in recent 30 years in Dalian,using the plate smoothing spline interpolation method and cokriging,the spatialization on major agriculture meteorological disasters were carried out. The major meteorological disasters were spatially analyzed with 1:250 000 geographic information data by ArcMap,and the digital maps were made with meteorological disaster and crops,and then actual application was elaborated by taking hail as an example. The method could be used to help government to make better decision in disaster prevention and reduction and cropping layout optimization. |
